To all whom {t mely concern B t kn ws t I, new Elam, a citizen of t e Unawa e, resi in at lu b n the may 1 LQW QQS" n St t of Mi i sippi, hav in ented a n w and u u Heep-F st ner, Qj Whish hs 9 lowing is a specification.

This invention relates'to a hasp fastener.

The object of the plhSQIlt iiiventioh is, 19'

provide an improved form of hasp in'v vhich the latch memb r drepsimo leak ng p itio audi s imiiq' 's b fer the alien be shaken or jarred from a locked position, A further object is to proyide a hasp fastener the construction of which extremely simple.

With the foregoing nd eth r ebie ts View which will appear the description Pr c ds, th nv tion te jides n th me bination and arrangement of parts and in the details of construction hereinafter described and claimed, it bfiii ig 'imderaq a that changes in the precise embodiment of- 5 is a detail view of the catch. 6 is a perspective view' of amodified form.

Referring to the drawings in which simit lar reference numerals deslgnate' corresponding parts throughout the several views, 1 is the strap or body portion of my improved hasp and is illustrated in Fig. 1 as being pivotally supported upon a door 2,

3 being the door frame or jam therefor.-

The strap 1 is provided at its ends with suitable pivotal supporting means therefor, in the present instance illustrated as a staple i fitting within a slot 5. The strap 1 is provided on the remote end therefrom with the usual slot opening 6 which fits over a suitable catch staple 7, all of which is of the usual and preferred form of hasp fastener.

Mounted upon one end of the strap 1 adjacent the slot 6 is the casing 8, the said asin 8 bei fa me w t f n e which r spa ce t he upper surfaceof the casing 8 adistance from the stra v 1. The saidcasr as isrigidly held to the strap by rivets or other suitable equivalentnieans 10; This casing is proyided approximately centrally the e ri r rti nb thea reu ac t t lower edge of the depending wall. It is to ease w h as la d Poi-@ 11 is slotted portion extends approximately from' be understood this connection that thei casing 8 is necessarily shell-like inform but may be solid illustrated inFig.

in the said member isprovided with t e .6 11 a d s i i h r Pro id W th somewhat larger channel of groove there'- t iieat i; th ai hai el o x di t surface of'thesaid ineiiiber. the 'of t s' estw iq s m y e mrle d. tfib t .d ra ns rom e s i t of myin n "The member 8 with its grQQY d or slotted po ti 1 P ovi es Suitable ret i m a for elbow catch 12; the same being illustrat ed, in deta ilin Fig. 5. Suitable trunl ffare 'forrned therewithand serve as V pivots about which the elbow catch may turn? Disease ai plois at i a th upper'edge of the arm 12 are the outstahding ust the Pu p s f w ch i t limit hP v 1 t=i mQYsm nt 1 1.1 3 the trunnions 15 whenthelower' portion of the arm "13 is forced i ntoi engagement catch staple A 'eswli fima fiedfqiim i s bi ni Fig. i whiiili for the portion 8 there been substituted the a two' retaining lips l 71'7, these lips forming suitable retaining means for the trunnionsrlhofthe elbow In the practical operation of my improved device the normal position which thecatch will automatically assume is illustrated 1n Fig. 2, that is with the arm 13 in a vertical position and the arm 12 in a substan.

ing of the strap 1 over the catch staple 7 the outer portion of the said staple contacts with one edge of the arm13 of the catch and forces the same outward tothereby rotate the said catch about the trunnions 15. This rotation will continue until the outstanding lugs 16 cont-act with theupper surface of the portion 8 or 17 depending upon which form of retaining member 1s employed. The arm 13 will then be disposed, say, approximatelyat tfidegrees to 100 tially horizontal position. Upon the'placl Y down farther upon theretaining staple-7 as the catch cannot further rotate about the trunnions the said catch will be bodily 11 and the'ivariousparts areso designed Q thatthe said catch/will be forced upwardand beyond the uppermost edge of the staple 7 after which the arm 13 will immediatelyrotate about the trunnion 15 into horizontal position and as the outer edge Y of the arm 18 is beveled the catch will im-' mediately drop into engagement with the 1,5v this positionand cannotbejarred or shaken staple8 substantially as illustrated in Fig. 2.1 The catch does of itself naturally stay in therefrom The advantages accruing from acons truction' of'this character are readily apparent and the device constitutes anextremelydesirable and useful hasp fastener. The arm 13 is provided with the aperture 18 adjacent one end thereofthrough which may be placed suitable locking means, it being understood in this connection that any locking device may be employed. The modifled form as illustrated in Fig. 6, illustrates I a construction which is also self-locking and one" which is more simple in construction than the other forms as illustrated. In the saidmodification thestaple 7. is elongated sothat the said staple is adapted to extend beyond the port-ion 1 a sufiicient distance to allow the leg 13 of the catch to drop therein and to thereby efiect a locking of the device. Having thus fully disclosed the constructionandoperation of my improved latch or fastener, hat-I claim to be new and original with me is 1;. In a hasp latch the combination with a suitable plate, of a catch staple extending throughxa slot-therein, a catch mounted for rotation and translation upon said plate Copies of this patent ma be obtained for adapted .to' engage said catch staple.

2. In a'hasp latch the combination with a. suitable plate, of a catch staple extending through a slot therein, an elbow catch mounted for rotation and translation upon said plate and adapted to engage said staple. forced upward Within the; grooved portion 3'. In a hasp latch the combination with a suitable plate, of a catch staple extending through a slot therein, an elbow catch memher, said catch member provided with trunnions extending outwardly therefrom, means for mounting said catch member upon said plate for rotation and translation, said catch member adapted to engage said staple.

4:. In a hasp latch the combination with a suitable plate provided'with a slot therein, a catch staple extending through said slot, an elbow catch member provided with trunnions extending therefrom, means for rotatably mounting said catch member upon said plate, means for allowing said catch member to shift'transversely of said plate, said catch member adapted to engage said staple.

5. In a device of the class described, a plate provided with a slotted aperture adj acent one end thereof, a bell crank catch.

.member provided with trunnions extending therefrom, said catch member provided with lugs extending therefrom adjacent one end thereof, means for mounting said catch member upon said plate, said catch member adapted to rotate in a limited manner upon said trunnions, said catch lugs adapted to limit said rotation, said lugs adapted to impart a translatory motion to saidcatch five cents-each, by addressing the Commissioner of Patents, Washington, DjG.
